With the support of the National Endowment for the Humanities and donations from over one hundred people and organizations, Clio is a free platform designed to help organizations create and share walking tours and thematic trails that connect people to nearby history, art, and other topics. There are now over 1400 walking tours in Clio and the free website and mobile application will also guide the public to a growing library of over 35,000 landmarks throughout the United States. There are also virtual tours of museums and sites, interpretive nature trails that connect people to human and natural history, and thematic trails. Each month, organizations like historical societies, museums, libraries, and universities publish dozens of new trails and tours that can include audio narration, images, text, and links to related primary and secondary sources. Clio is a small non-profit organization sustained by an active volunteer community dedicated to connecting the public to nearby history, art, and culture.
